Bantam-X

A NASA project, managed by the Marshall
Space Flight Center, to develop a reusable small satellite launcher.
The goal of NASA's Bantam-X program was to identify key vehicle technologies
that would enable significantly lower cost launch services for very light
satellites (to the order of $1,000,000 per launch for a single 200 pound
payload), typical of those designed to carry small university science payloads.
In these type of missions, the cost of the experiment is relatively low
and the launch frequency is potentially very high. The envisioned Bantam
vehicle was a multi-stage reusable launch system.
